Ligneous Periodontitis in a Child With Plasminogen Deficiency.

Abstract

Ligneous periodontitis (LP), a rare periodontal disease, is seen secondary to plasminogen deficiency and fibrin deposition. It is characterized by nodular gingival enlargements and progressive destructive membranous periodontal disease. It generally ends with the early loss of teeth. Defective fibrinolysis and abnormal wound healing is the main pathogenesis of this rare disease and should be considered different from other mucosal systemic disorders. In this case report, we describe the management of ligneous periodontitis and ligneous conjunctivitis developing secondary to plasminogen deficiency in a 6-year-old girl.
